Windows module pipelines - change spec matrix to enable Ruby 2.3.1 / Puppet 4.6.1 gem

The current spec matrix for the following modules should be updated, including:

• ACL - https://jenkins-modules.puppetlabs.com/view/3.%20windows%20only/view/acl/view/acl%20-%20master/job/forge-windows_puppetlabs-acl_intn-module_master/ - note matrix still includes 2003
• Chocolatey - https://jenkins-modules.puppetlabs.com/view/3.%20windows%20only/view/chocolatey/view/chocolatey%20-%20master/job/forge-windows_puppetlabs-chocolatey_intn-module_master/
• DSC - https://jenkins-modules.puppetlabs.com/view/3.%20windows%20only/view/dsc/view/dsc%20-%20master/job/forge-windows_puppetlabs-dsc_intn-module_master/ - note only x64 is tested
• Powershell - https://jenkins-modules.puppetlabs.com/view/3.%20windows%20only/view/powershell/view/powershell%20-%20master/job/forge-windows_puppetlabs-powershell_intn-module_master/
• Reboot - https://jenkins-modules.puppetlabs.com/view/3.%20windows%20only/view/reboot/view/reboot%20-%20master/job/forge-windows_puppetlabs-reboot_intn-module_master/ - note this still includes 2003
• Registry - https://jenkins-modules.puppetlabs.com/view/3.%20windows%20only/view/registry/view/registry%20-%20master/job/forge-windows_puppetlabs-registry_intn-module_master/
• Sqlserver - https://jenkins-modules.puppetlabs.com/view/3.%20windows%20only/view/sqlserver/view/sqlserver%20-%20master/job/forge-windows_puppetlabs-sqlserver_intn-module_master/
• wsus_client - https://jenkins-modules.puppetlabs.com/view/3.%20windows%20only/view/wsus_client/view/wsus_client%20-%20master/job/forge-windows_puppetlabs-wsus-client_intn-module_master/

The matrix should additionally specify a Puppet gem version of '~> 4.6.0' in conjunction with the Ruby 2.3 runtime.

Note that the matrix may not succeed until the 4.6.1 gem is published (which is currently scheduled for 8/23/2016)
